So the polio vaccine caused the current outbreak? Am I reading this correctly?
'Genetic analysis of a polio virus sample from the patient indicates that it was picked up from a person who had received the oral polio vaccine, which has not been used in the U.S. since 2000, health officials said.
The oral vaccine contains a weakened live polio virus. "If allowed to circulate in under- or unimmunized populations for long enough … the virus can revert to a form that can cause illness and paralysis in other people," the CDC says.'
